What is an Expert Witness?

An expert witness is a highly qualified academic or experienced practitioner in a specified field whose impartial opinions are respected by courts and thus permitted to be expressed in front of judges and juries. Depending on their technical field, a typical expert witness has both university degrees (often a Ph.D.) as well as hands-on experience working in industry. The courts of different jurisdictions, such as United States District Court vs. the Patent Trial and Appeal Board, define the rules for permissible experts and testimony in their venues.

Barr Group assists the legal community in finding the best expert for cases that require analysis of software or electronics and/or related opinions. We maintain an expert witness directory that provides profiles for a representative set of our engineer. However, not all of Barr Group's experts are profiled on our website. If you have a case that needs an expert please contact us now for a free consultation.

Embedded C Coding Standard The Industry Benchmark

A C coding standard is a set of rules for source code that is adopted by a team of programmers working together on a project, such as the design of an embedded system. Barr Group's Embedded C Coding Standard was developed to minimize bugs in firmware by focusing on practical rules that keep bugs out and is one of the top used coding standards in the embedded systems design community.
